## 🎯 Minimum Required Setup

**For basic functionality, you only need**:
1. **Supabase** (free tier) - Database
2. **One AI Provider** (OpenAI recommended) - AI Generation
3. **Environment variables** in your deployment platform

**Optional enhancements**:
- MongoDB for backup storage
- Multiple AI providers for redundancy
- Deployment tokens for automated CI/CD

## 🚨 Security Notes

- **Never commit API keys** to version control
- Use **environment variables** in production
- **Rotate keys** regularly
- Set **usage limits** on AI provider accounts
- Use **service role keys** for Supabase (not anon keys)

## 📊 Cost Estimates (Monthly)

- **Supabase**: Free (up to 500MB)
- **MongoDB Atlas**: Free (up to 512MB)
- **OpenAI**: $5-50 (depending on usage)
- **Groq**: $0-20 (generous free tier)
- **Vercel**: Free (hobby projects)
